• Affrettando — An Italian musical direction instructing the performer to increase the tempo in a hurried, rushing, or pressing manner, carrying an implication of excitement or heightened nervous energy.
• Aperto — A musical term of performance direction indicating that a piece must be executed in an open, clear, broad, and bright manner. In a broader literary sense, it stems from foreign phrases meaning unfolding without restrictions or secrets (e.g., in aperto).
